Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling for communications in a wireless communications system. The control signaling may indicate a first duration for an inactivity timer. The UE may initiate the inactivity timer and a second timer based on identifying a period of inactivity. The second timer may have a second duration that is shorter than the first duration for the inactivity timer. In some examples, the second duration may be based on one or more parameters, such as a display status, a battery status, a scaling factor, the first duration, an application state, or any combination thereof. The UE may release a connection for the communications in the wireless communications system based on an expiration of the second timer, an expiration of the inactivity timer, or a combination thereof.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may divide a measurement of a cell into two or more portions. The UE may receive a control message that indicates a request to perform the measurement and a target frequency associated with the measurement. In some examples, the UE may generate at least a first radio frequency (RF) script during an on duration of a discontinuous reception (DRX) cycle based on the target frequency. The UE may perform at least a portion of the measurement during an off duration of the DRX cycle based on the first RF script. Additionally or alternatively, the UE may generate the first RF script and perform the portion of the measurement during an off duration of a DRX cycle and the UE may generate a second RF script during an off duration of a second DRX cycle.

Abstract: Techniques are provided for receiving encrypted positioning assistance data, requesting and obtaining cipher keys to decrypt the positioning assistance data. An example method for transmitting a cipher key request includes receiving cipher key information including a start time value, a duration value, and an advance time value, determining an advance time duration that is equal to a sum of the start time value and the duration value minus the advance time value, and transmitting the cipher key request within the advance time duration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a broadcast or multicast (broadcast/multicast) application associated with a first radio access technology (RAT) while the UE is in a standalone mode for a second RAT; switch from the second RAT to the first RAT based at least in part on initiating the broadcast/multicast application; and switch from the first RAT to the second RAT based at least in part on failing to detect a communication associated with the broadcast/multicast application using the first RAT. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station associated with a first radio access technology (RAT), a neighbor cell list including entries for at least a first set of neighbor cells and a second set of neighbor cells, the first set of neighbor cells and the second set of neighbor cells associated with a second RAT. The UE may determine that the first set of neighbor cells is associated with a first network operator and that the second set of neighbor cells is associated with a second network operator. The UE may measure at least one neighbor cell of the neighbor cell list based at least in part on prioritization of the first set of neighbor cells relative to the second set of neighbor cells. Numerous other aspects are described.

Abstract: Aspects presented herein may improve a UE's performance by optimizing the CDRX toggling at the UE. In one aspect, a UE transmits, to a base station, a first UE assistance information request, where the first UE assistance information request include s at least one of an updated CDRX cycle or an updated inactivity timer period, and the updated CDRX cycle is different from an initial CDRX cycle and/or the updated inactivity timer period is different from an initial inactivity timer period. The UE adjusts the initial CDRX cycle to the updated CDRX cycle based on the first UE assistance information request. The UE transmits, to the base station after the initial CDRX cycle is adjusted, a second UE assistance information request, where the second UE assistance information request includes at least one of the initial CDRX cycle or the initial inactivity timer period.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, via a first subscription of the UE, a trigger event for a conditional handover of the UE from a source network entity to a target network entity. The UE may determine, based at least in part on the trigger event, that a target band associated with the target network entity is not compatible with a serving band associated with a second subscription of the UE. The UE may store the trigger event for the conditional handover in a buffer of the UE. The UE may perform an action related to the conditional handover based at least in part on a condition being satisfied. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may configure a user equipment (UE) with a time to trigger (TTT) and a signal quality threshold. The UE may determine whether one or more conditions are satisfied, and if so, transmit an early measurement report or ignore a conflicting procedure that renders the measurements unavailable. In some examples, a UE may receive an indication of a minimum TTT in a configuration message with the TTT and the signal quality threshold. The UE may indicate an updated timing, to a base station, based on the minimum TTT. In some examples, the base station may determine that a UE is a multi-subscriber identification module (MSIM) UE, and may configure the duration of the TTT accordingly.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, via a subscription of the UE to a network node, a UE assistance information (UAI) that indicates a reduction to one uplink multiple-input multiple-output (MIMO) layer for the subscription. The UE may transmit, via the subscription to the network node, an uplink transmission using one uplink MIMO layer on one transmit (Tx) chain of the UE based at least in part on the UAI and a timer associated with the UAI. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that the UE is connected to a wireless network on a first carrier frequency in a first frequency range that is associated with a lower data rate than a second carrier frequency in a second frequency range. In some aspects, the first frequency range may be associated with a first version of a radio access technology (RAT) and the second frequency range may be associated with a second version of the RAT. The UE may determine a bandwidth metric associated with the first carrier frequency in the first frequency range. The UE may display a first visual indicator associated with the first version of the RAT or a second visual indicator associated with the second version of the RAT based on the bandwidth metric. Numerous other aspects are described.
